EUGNE SCENEIDER, OF LE CREUZOT, FRANCE.

GUN-IJOUNTING.

Lieaose.

Application filed January 2C, 1915. Serial No.

To all echo/m. it may concern Be it 1Known that EUGNE Soi-murrine, a citizen of the Republic of France, residing at Le Creuzot, Sane-et-Loire, France, have invented a'new fand useful Improvement in or Relating to Gun-Mountings, which is fully set forth in the following specification. f

This invention relates to gun mountings of the kind in which roller or ball'bearings are employed upon which the carriage moves during training. In gun mountings of this type it is desirableV to relieve the .roller or ball bearings from the recoil strains. lilith this obyect it has been proposed to interpose between the outer bearing ring of each roller bearing and the mounting or the carriage an annular spring the compression of which during firing absorbs the recoil strains transmitted by the brake. rifhis known arrangement has the disadvantages of necessitating annular. springs and of speedily becoming inoperative. The annular springs become deformed under the influence of the radial strains whose directions vary in accordance with the tiring direction and there are no available means for correcting the effects of local deformation, so

that the centering of the pivot speedily be-A comes defective. This defective centering immediately gives rise to Jfriction in places in which the ball bearing or bearings should eliminate such friction. ldoreover the annular springs are diiiicult of access and their condition may become highly detective without any outward indication of the fact, the result being that in the course of tiring a spring may break without the slightest warning.

According to the invention the ball or lroller bearings are provided with a shock absorber which is displaceable ywith the gun carriage and arrangedin the direction of firing which position it always occupies at all angles of training. The device in question consists oit' a metal or other spring arranged between the carriage and a shoulder formed upon the outer end ot' a radial extension of the supporting ring or" the ball or roller bearing, the said extension being arranged in the plane of the vertical axis ot' the gun.

In order that the said invention may be clearly understood and readily carried into effect, I will describe the same more fully Specification of Letters Patent.

with reference to the accompanying drawings, in which Figure l is asectional elevation on the line I-I of F ig. 2 illustrating the application of `the invention to a gun carriage mounted on a platform and displaceable about a fixed pivot between-which and the carriage a ring of rollers is arranged. Fig. 2 is a sectional plan on the line II--I of Fig. l. Figs. 2- to 6 illustrate the invention applied to a pedestal mounting, and in these gures. Fig. Sis a sectional elevation on the line III-IH in Fig. el, which is a sectional plan on the line V-V of Fig. 3. Figs. 5 and 6 are partial sections on the lines V-V and Vldv respectively of Fig. 3.

Referring to Figs. l and 2, A is the carriagewhich carries a turntable a mounted upon truste-conical rollers C bearing upon a base plate B provided with a double pivot b b. Between the pivot b and a bearing ring D rollers E are interposed. The means for relieving these rollers from the firing strains is constituted in the following manner: llie ring D comprises a radial extension (Z passing through a bearing a on the carriage A or its turntable a and arranged in the plane of the vertical axis of the gun. At the outer extremity of this extension d an adjustable collar ai is arranged and a spring F is disposed between this collar and the outer face of the bearing a. During firing, the gun carriage A is displaced by the gun and at once bears upon the pivot I) by means of the socket a2 and compresses the spring F- by means of the bearing a. Between the shoulder D of the ring D and the bearing a. a clearance exists equal to the clearance that existed between a2 and b. After firing. the spring F brings the gun carriage A back against the shoulder D. lt will be noted that the roller bearing is relieved from the iiringstrains and that the shock absorbing springs. which are visible and readily accessible, experience only axialv strains that is to say strains in the direction oit their flexibility; in other words, they do not experience any abnormal deformation.

Referring to Figs. 8 to 6 the lower face of the carriage A carries a pivot AYinovable in an upper collar B of a pedestal B and bearing by means of its lower extremity upon a bearing ring B2. The pivot A is guided upon a vertical trunnion b rigid with the pedestal. Between the trunnion b and the Vsocket a2 of the pivot A and between a projection a. formed beneath the carriage A and the collar B', roller bearings are arranged which as in the preceding' example) comprise a ring D provided with an extension CZ engaging in a bearing formed upon the gun carriage and arranged in the plane of the vertical axis of the gun. The lower shock absorbing device is directed oppositely Y to the upper shock absorbing device. During iiring,fthe pivot A bears upon the collar B and upon the trunnion b by means of a collar A2; the clearance normally existing between the rear of the pivot A and the collar B disappears and a corresponding clearance occurs between the projection d and the shoulder D of the upper ring D. The normal clearance between the parts b" and A2 disappears and a corresponding clearance occurs between the shoulder D of the lower ring and a2.

What I claim and desire to secure by Letters Patent of the United States is :h

l. In combination, a revoluble gun-Supporting frame, a base having a pivot for carrying said frame, anti-friction means lbetween said pivot and said frame, andV adjustable shock-absorbing means for relieving said anti-friction means from firing strains.

2. In combinationa revoluble gun-supporting frame, a base/having a pivot for carrying said frame, anti-friction bearing means between said pivot and said frame, and adjustable shock-absorbing means external of the frame for relieving said bearing means from iring strains.

3. In combination, a revoluble gun-supporting frame, a base having a pivot for carrying said frame, anti-friction means between said pivot and said frame, and an adjustable yielding means engaging said frame and said anti-friction means for relieving said anti-friction means from firing strains.

4. .ln combination, a revoluble gun-supporting frame, a base having a pivet for carrying said frame, antifriction bea-ring means between said pivot and said frame, a spring normally resisting movement oi said frame and reacting through said bearing means on said base, and means foradjusting the tension oi said spring. j In combination, a'revolubly supported gun-carriage frame, an upright shouldered pivot memberv about which said frame rotates, roller bearing means between said frame and said pivot, adjustable yielding means engaging said frame and said bearing means, anda col-lar on said frame for receiving the shoulder of said pivot. o

6. In combination,` a revoluble gun-supporting frame, a base having a pivot, antifriction bearing means surrounding' said pivot, a ring member surrounding said bearing means and having a projecting lug which Vextends through a portion of said frame,

projection extending a1 revoluble gun-supannularV means for retaining saidI bearing meansin position, a projection' on said' annular means passing through a portion of Y said frame and, receiving a ,shock-absorbing means, and otherbearing means for main taining other portions o'fthe frame in normal position. c

9. In combination, a revoluble gun-supporting frame, a basemember having aV pivot, antifriction bearing' means engagingv said pivot, annular means between said` bearing means and said frame, a projection onsaid annular means extending through-'a portion of said frame, andadj'ustable' shock-absorbing means associated with said projection and said frame, saidabsorbing'meansfbeing accessible from outside said frame-and said base. l

10. In combination, a. revoluble gunsupf porting frame, a base member for support; ing said frame, anti-friction bearing. means operating against externalx parts of` said base,-annular means for retaining saidbearing means in position, and a projection on said annular means passing through afpor tionV of said frame and receiving'a shockabsorbing means.

In testimony whereof I have signed this specification inthe presence of two subscribing witnesses. y Y Y VEUGENE SCHNEIDER. itnesses CHARLES GABANAZ,
